Linux kernel source tree
628a27731e
Add a Kconfig to allow building KVM without support for emulating a I/O APIC, PIC, and PIT, which is desirable for deployments that effectively don't support a fully in-kernel IRQ chip, i.e. never expect any VMM to create an in-kernel I/O APIC. E.g. compiling out support eliminates a few thousand lines of guest-facing code and gives security folks warm fuzzies. As a bonus, wrapping relevant paths with CONFIG_KVM_IOAPIC #ifdefs makes it much easier for readers to understand which bits and pieces exist specifically for fully in-kernel IRQ chips. Opportunistically convert all two in-kernel uses of __KVM_HAVE_IOAPIC to CONFIG_KVM_IOAPIC, e.g. rather than add a second #ifdef to generate a stub for kvm_arch_post_irq_routing_update().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
